I just stuck a chrome orb on my 800 mhz athlon & KT7-RAID motherboard (After filing down the edge a tiny bit. Stupid cramped board..) and according to its built in sensor, it runs at roughly case temp while idling, but as soon as I load up a game it quickly picks up heat. I've usually stopped once it hit 50-52C, and the temperature quickly went back down again. How hot _are_ these things supposed to run, anyway?
